    Polyurethane foam (OCF) is polyurethane foam aerosol technology and technology intersect with the product. It is a polyurethane prepolymer, blowing agents, catalysts and other components in the aerosol canister is loaded in the pressure of a special polyurethane product. When the material is ejected from the aerosol canister, the polyurethane foam-like material will rapidly expand and come into contact with air or moisture in the substrate is cured to form the foam. OCF foam has cured caulk, bonding, sealing, insulation, sound absorption and other effects, is an environmentally friendly energy-saving, easy to use building materials, suitable for sealing, plugging, fill in the blank fill joints, fixed bond, noise insulation, especially for steel or aluminum alloy doors and windows seal between the wall and waterproof plugging. For wide interface, crevice, crack sealing, insulation, padding, to heat, cold resistance, dry, sound insulation and moisture. Like the gap between the partitions and ceilings, window frames, door frames, between the cavity wall, the gap between the roof and chimneys, walls, ceilings, roofs and the sealing around pipes and damage at the hole in the wall. Can be used for bonding a variety of materials such as metal, wood, stone, concrete, and a variety of synthetic materials such as polyester, polystyrene foam, PVC plastic, rigid polyurethane foams. Bison styrofoam does not apply to polyethylene, silicone and Teflon material.
    One kinds of sealing surface with the shape deformation, not flowing, there is a certain adhesion of the sealing material. Configuration is used to fill the gap, in order to play the role of the adhesive seal.
    With anti-leak, waterproof, anti-vibration and sound insulation, heat insulation effect.
    Typically bituminous, natural resins or synthetic resins such as natural rubber or synthetic rubber or dry dry viscous material as the base material, with talc, clay, carbon black, titanium dioxide and inert fillers such as asbestos, then add plasticizers, solvents, curing agent and catalyst is made.
    Can be divided into elastic sealants, liquid sealing gasket and sealing putty three categories.
    Widely used in construction, transportation, electronic instrumentation and components of the seal.
    Architectural sealants for building a variety of sealing seams or holes to prevent gas, liquid, solid through and prevent displacement of structural materials in the structure is destroyed, and thus play a thermal insulation, sound insulation, waterproof, dustproof , anti-gas, fire, corrosion, vibration and prevent accumulation of foreign joint function.
    Construction sealant composition according to their classification, now has polysulfide rubber, chloroprene rubber, acrylic, polyurethane, butyl rubber, silicone rubber, rubber composite, thermoplastic elastomers and other; construction form can also be divided into thermal coating type, cold coating type, curing reaction type and solvent evaporation, etc.; also use is divided into windows and doors, caulking to use, waterproof shockproof, precast wall with an equal. The table lists the basic types of construction sealants. Glass, plastic is a common household adhesives, mainly composed of sodium silicate (Na2O · mSiO2), soluble in water, sticky, also known as sodium silicate South, the North also called sodium silicate.
    Sodium silicate with water as a dispersant system for the colorless or slightly colored transparent or translucent viscous liquid.
    Solid sodium silicate is a colorless, or slightly colored transparent or translucent glass block body.
    Form into liquid, solid, water quenching three. Theoretically such substances known as "gel."
    Normal sodium silicate blue block or slightly granular solid, high temperature high pressure solution is slightly colored transparent or translucent viscous liquid.
    1, glass, plastic or bad from the viscosity, tension, whether mold, is it easy to clean, will change color and other aspects of investigation, from the color point of view, glass glue a variety of colors, white, black, color, etc., as well as transparent color.
    2, acidic silicone sealant: bonding a wide range, for most building materials such as glass, aluminum, wood and other non-oleaginous has excellent adhesion. But can not be used for bonding ceramics, marble and so on.
    3, neutral silicone sealant: Can be used for bonding ceramic sanitary ware, marble.
    4, the market many varieties of glass, plastic, glass, plastic acidic, neutral weather rubber, neutral silicate structural adhesive, silicone rubber stone, neutral mold plastic, hollow glass, plastic, aluminum panels for plastic, aquarium special glue, large glass adhesive, bathroom mold for plastic, rubber, etc. acidic structure.
    Glass, plastic, although very modest, but it is most frequently used in the home improvement process of an excipient, such as bonding and kitchen wall cabinets countertops, basin and toilet and other fixed operations, should use it. Because some consumers do not understand the performance of glass, plastic, often just "two bottles", no matter what materials are bonded using the same kind of glass glue. In fact, different conditions apply different properties of glass, plastic. If you use the wrong glass, plastic, lead seals broken, moldy, or even leaking windows, countertops leaks and other problems, so consumers should be in accordance with the specific purpose to buy plastic glass.
